Retry function (Pr. 65, Pr. 67 to Pr. 69)

If a fault occurs, the inverter resets itself automatically to restart. You can also select the fault for
a retry.
When you have selected automatic restart after instantaneous power failure (Pr. 57 "Restart
coasting time" ≠ 9999), restart operation is performed at the retry operation time which is the
same of that of a power failure. (Refer to section 6.12.1 for the restart function.)
